Disgusting attitude from a petrol attendant

I have always had a bad experience at this specific Engen. The petrol attendants take their sweet time to serve, they will finish their fat conversations before attending to a customer and worst of all, I always have to ask them to clean the windscreen although they can see it is filthy. On 26/05/2015 just after 12 o'clock, I went to fill up my car. Now this garage is closest to my place and most convenient. I get there there guys are chatting as usual and as I am about to live the car and go look for someone, Jonas(attendant) comes to serve me. i tell him what I want and he is still laughing with his friend. As i am walking towards the door to the shop to get what i needed he asks me what it is I wanted. I then ask him if he was not listening. There goes the \black brother"playing the guilt trip on me of how I am black and should stop acting white because I could see he was still talking to his friend and as a 'black sister' I should respect that as he is a man. I went in to buy and asked to speak to a manager \""CHRIS\"". While busy explaining the situation to Chris the 'brother\"" is yelling at the back ground how I think I am all that and lack respect for black man. DISGUSTING!!!"""
